Hey, I would be glad to see the walker core powered pizza oven! Could you please give an update on that? Cheers!
Sounds great, what temperature do you get at the top of the dome though? About the same as the floor temp. There is not much of a dome to speak of. It's a box of 11cm high. My design is too premature to be shown here. When I get everything dialed in better, I'll post it in the experiments/results section. When it's ready, I'll post it back here. Just one more thing I learned today: 450°C is way to hot to bake pizza. The dough burns right away. 360°C for the floor seems to be the sweet spot while 450°C is perfect for the rest of the oven (to cook and grill the toppings and cheese). I'll figure a way to lower the temp of the floor - I am sure - so I still believe soon this will be a perfect rocket pizza oven! Cheers Piet

The simplest way to get a quick warming floor is a flame path below a thin plate. Karl, I used your recommendation of the shelf and the oven is performing much better. The plot below shows how much faster the floor heated up (300 oC in 30 minutes). The oven is also much more efficient. My exhaust temp is now 80 oC-120 oC where it used to be ~400 oC. One thing to note is that it seems like every time i get above 1100 oC in the heat riser, i get a thermal run away. Does anyone have any recommendations on how to prevent a run away? I try to only add large chunks once the fire has had one burn but it is unpredictable.... The pizza doesn't cook as fast as some ovens I have heard about but this was done in ~5 minutes. I am pretty happy with that since the oven hold heat for so long that i think it would be good for baking other stuff. Video of fire boxI fixed this post and will try to remove the duplicate picture post.

There is sth wrong with your links. They all direct to the 5th page of this topic not to a photo. Placing images is a bit tricky in here. You need to place them in any photo storage service and copy the links from tehre and then place teh links using "insert image" button. [/quote]

No Jon, those links won't work. In fact those are leading to the latest post in this thread, the one by Jura.
edit: I checked, now it points to mine.

I just realized my album was private (embarrassed). I just made it public. Any luck now?

I just wanted to give one more update. The oven is running well! In a recent run I was able to cook some apple crisp in between some pizzas. One think that i have noticed is that the oven floor now gets much hotter than the dome. I am considering adding a thin layer of mass (perhaps 1/2 inch) to the bottom of the dome so that it radiates more since the GeoPolymer is such a good insulator. Below i linked some pix. My daughter made some mosaics out of glass she found on the river bank... link
